Air: Invisible yet so Effective
"Wow, I had no idea that air could do that." Using novel equipment that includes a vacuum pump, other vacuum apparatus, and liquid air, Peter performs demonstrations, and conducts investigations, that grab students' attention, get them thinking, broaden their understanding, and foster a keen interest in science.
This dynamic, 1-hour show is a combination of lecture, demonstration, question and answer, and student involvement that has students making predictions about, and developing explanations for, the observed phenomena. See the refusing funnel, objects released in a vacuum, a suspended student (and teacher!), expanding and shrinking balloons, a frozen squash ball break, a tin explode, and more, plus make a cloud.
The show reinforces concepts that include air as an occupier of space, objects falling in air compared with in a vacuum, the particle model of matter, pressure, expansion and contraction, and phase changes. It also addresses common student misconceptions and enriches students' understanding by extending syllabus topics both conceptually and contextually.
